El Ceibillo, Guatemala

US Geothermal Inc. is developing the El Ceibillo geothermal project in the Republic of Guatemala. US Geothermal was granted geothermal energy rights to the concession in April 2010. The concession contains 24,710 acres in the center of the Aqua and Pacaya twin volcano complex. The El Ceibillo geothermal project area has nine existing geothermal wells that were drilled in the 1990s and have depths ranging from 560 to 2,000 feet (170 to 610 meters). Six of the wells have measured reservoir temperatures in the range of 365°F to 400°F.

Mannvit was tasked with consulting on the development of the well field and to construct the reservoir model for the project.

"The El Ceibillo geothermal project area has nine existing geothermal wells that were drilled in the 1990s and have depths ranging from 560 to 2,000 feet (170 to 610 meters). Six of the wells have measured reservoir temperatures in the range of 365°F to 400°F and have high conductive gradients that indicate rapidly increasing temperature with depth. Fluid samples and mineralization from the wells indicate the existence of a high permeability reservoir below the existing well field."
